  2. Mass concentration (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_concentration_(chemistry)

    1% m/v solutions are sometimes thought of as being gram/100 mL but this detracts from the fact that % m/v is g/mL; 1 g of water has a volume of approximately 1 mL (at standard temperature and pressure) and the mass concentration is said to be 100%. To make 10 mL of an aqueous 1% cholate solution, 0.1 grams of cholate are dissolved in 10 mL of ...

  3. Fluid ounce - Wikipedia

    en.wikipedia.org/wiki/Fluid_ounce

    The gallon was divided into four quarts, the quart into two pints, the pint into four gills, and the gill into five ounces; thus, there were 160 imperial fluid ounces to the gallon. This made the mass of a fluid ounce of water one avoirdupois ounce (28.35 g), a relationship which remains approximately valid today despite the imperial gallon's ...

  4. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    To create the solution, 11.6 g NaCl is placed in a volumetric flask, dissolved in some water, then followed by the addition of more water until the total volume reaches 100 mL. The density of water is approximately 1000 g/L and its molar mass is 18.02 g/mol (or 1/18.02 = 0.055 mol/g). Therefore, the molar concentration of water is

  5. Mass fraction (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_fraction_(chemistry)

    This improper name persists, especially in elementary textbooks. In biology, the unit "%" is sometimes (incorrectly) used to denote mass concentration, also called mass/volume percentage. A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). This is incorrect because ...

  6. Brix - Wikipedia

    en.wikipedia.org/wiki/Brix

    For example, when one adds equal amounts of salt and sugar to equal amounts of water, the degrees Brix of the salt solution rises faster than the sugar solution, because it is denser. The °Bx is traditionally used in the wine , sugar , carbonated beverage , fruit juice , fresh produce , maple syrup , and honey industries.

  7. Cooking weights and measures - Wikipedia

    en.wikipedia.org/wiki/Cooking_weights_and_measures

    A US fluid ounce is ⁠ 1 / 16 ⁠ of a US pint (about 1·04 UK fluid ounces or 29.6 mL); a UK fluid ounce is ⁠ 1 / 20 ⁠ of a UK pint (about 0·96 US fluid ounce or 28.4 mL). On a larger scale, perhaps for institutional cookery, a UK gallon is 8 UK pints (160 UK fluid ounces; about 1·2 US gallons or 4.546 litres), whereas the US gallon is ...

  8. Nickel(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Nickel(II)_sulfate

    Nickel(II) sulfate, or just nickel sulfate, usually refers to the inorganic compound with the formula NiSO 4 (H 2 O) 6. This highly soluble turquoise coloured salt is a common source of the Ni 2+ ion for electroplating. Approximately 40,000 tonnes were produced in 2005. [1]

  9. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    The first solvation shell of a sodium ion dissolved in water. An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl ...
